Emergency Fund Calculator
Estimate how large your emergency fund should be based on your essential monthly expenses, risk profile, and income stability. You can also estimate how long it may take to build the fund with monthly savings and optional account yield.
Burrow Tip: Your emergency fund is not an investment target. It is a resilience target. The right size depends more on risk and obligations than on return.
Run both a minimum-safe target and a stronger target so you can see the difference between “barely covered” and “well protected.”

How to use these results
An emergency fund is a stability buffer, not a return-maximization project. The key question is not just “How much do I have?” but also “How long could I operate if income stopped or dropped?”
- Base the target on essentials: use true must-pay expenses, not your full lifestyle budget.
- Adjust for risk: variable income, dependents, or a weak job market usually justify a larger buffer.
- Use current coverage as a reality check: months covered is often more informative than the dollar amount alone.
- Build in stages: one month, then three months, then six months is often a more practical path than aiming for the full target immediately.
This tool is best for cash-reserve planning. It does not model job loss timing, partial emergencies, or portfolio drawdown strategies.
